Abstract

A method of inter-RPR-ring bridge redundancy configures a priority for each inter-ring bridge; constitutes a redundancy group by more than one inter-ring bridges on both two RPR rings, and configures one inter-ring bridge as a primary inter-ring bridge in the redundancy group which is in charge of forwarding packets, while the other(s) is (are) set to be secondary inter-ring bridge(s). When the redundancy group changes, an inter-ring bridge with the highest priority and having an inter-ring communication ability is elected to be the primary inter-ring bridge. According to the method provided by the present invention, an RPR ring can recover rapidly after the RPR bridge changes. As a result, the services on the RPR ring are ensured to be used normally, the network communication delay is reduced, and the burden of the network communication is reduced.
